Restarting Linux logical partitions

You can restart Linux logical partitions or the Linux operating system using the Hardware Management Console (HMC). Restarting a logical partition shuts the logical partition down and then starts it again.

1. In the navigation pane, expand Systems Management > Servers.
2. Click the managed system on which the logical partition is located.
3. In the work pane, select the logical partition.
4. From the Tasks menu, click Operations > Restart.

   The HMC Classic interface is not supported in Hardware Management Console (HMC) Version 8.7.0, or later. The functions that were previously available in the HMC Classic interface are now available in the HMC Enhanced+ interface.

   When the HMC is at version 8.7.0, or later, complete the following steps to restart a logical partition:

   1. In the navigation pane, click the Resources icon .
   2. Click All Partitions. Alternatively, click All Systems. In the work pane, click the server name that has the logical partition. Click View System Partitions. The All Partitions page is displayed.
   3. In the work pane, select the logical partition and click Actions > Restart.
5. Select one of the following options:

   Option	Description
   Operating System	The HMC issues the Linux shutdown -r +1 command to shut down and restart the logical partition. This option is available only when the operating system is running, and not when the logical partition is in an Open Firmware state.
   Operating System Immediate	The HMC issues the Linux shutdown -r now command to shut down and restart the logical partition as quickly as possible, bypassing messages to other users.
   Immediate	The logical partition is restarted as quickly as possible, without notifying the logical partition.
   Dump	The HMC allows the Linux operating system on the Linux logical partition to run a diagnostic procedure. After the diagnostic procedure is complete, the logical partition restarts. The exact diagnostic procedure depends upon which Linux operating system is installed on the logical partition and how the operating system is set to do. The operating system might run an OS debugger, the operating system might perform a main storage or system memory dump on the logical partition, or the operating system might not be set to run any diagnostic procedure at all.

6. Click OK.
